VAPORIZER.

Specification of Letters Patent.

Patented June 7, 1921.

I 0 all whom it may concern:

Be it known that I, ARGHIBALD W. GRirriN, a citizen of the United States, and a resident of the city of Toledo, county of Lucas, and State of Ohio, have made an Invention Appertaining to Vaporizers;and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention has for its object to provide a liquid fuel vaporizing plug. Plugs containing my invention are provided with a bare resistance wire that may be connected with a source of current supply and which is located in a chamber or-passageway that is filled with liquid fuel intermediate the source of supply and the end of the nozzle of the carburetor. The invention is particularly of value when used to vaporize the liquid fuel supplied to a carbureter of an internal combustion engine and to heat the fuel preparatory to starting the engine, especially in cold weather. The invention has for its object to provide other features that will appear from the following description and upon examination of the drawing.

The invention may be contained in structures of different forms and to illustrate a practical application of the invention I have selected a structure containing the invention as an example and shall describe it hereinafter. The structure selected is illustrated in the accompanying drawings.

Figure 1 of the drawings is a view illustrating the plug applied to a carbureter showing a side view of the portion of the plug located on the outside of the carbureter. Fig. 2 is a sectional view of the plug.

In the construction shown in the drawings, 1 is a shell having the chamber 2. An insulating tubular member 3 formed of ceramic material, preferably, material known in the trade as lava, extends into the shell 1 and preferably so as to bring the upper end of the member near the upper end of the threaded protuberance 4 of the shell 1. The tubular member 3 is provided with a flange 5 that forms a pair of shoulders on the tubular member 3 and packing rings 6 are located on opposite sides of the flange 5.

A packing nut 16 is threaded into the shell 1 so as to seal the tubular member 3 and prevent leakage of fuel around the tubular member 3. The upper end of the tubular member 3 is provided with a resistance wire 7. The upper end of the tubular member 3 is provided preferably with a relatively large chamber 8 and the resistance wire is locatedin the chamber 8 and is preferably in the form of a coil, thus presenting arelatively large area of contact between the" liquid fuel and the resistance wire.

The resistance wire is connected at one end to a pin 9 that extends through the lower end of the ceramic tubular member.

It is preferably provided with a head 10 that may be threaded onto the end ofthe pin 9 and which has a channel 11 for means 'of connection with electric circuits or battery 17 through electric connectors well known in the art.

The upper end of the resistance wire 7 is connected to the upper end of the threaded protuberance 4 by any well known means such as spotwelding or by brazing or by wedging theupper end into a cut formed in the upper protuberance.

The plug thus formed is connected to the fuel passageway of a carburetor intermediate the end of the nozzle and the fuel supply. In a large majority of the carbureters known in the art, an outlet is provided for the removal of sediment that may collect beneath or in the vicinity of the nozzle of the carbureter which is closed by a threaded solid plug. The plug involving my invention is so made that it may be inserted in place of the drainage plug of. such carbureter. The tapped opening for drainage is usually located directly beneath the nozzle of the carbureter or very close to the nozzle of the carbureter and communicates from beneath with the fuel passageway of the carburetor.

In Fig. 1 is shown a portion 15 of a car- The preferred form of vaporizing plug involving my invention is a small compact device, easily manipulated and connected with the carbureter and the source of electric current and when located in the drain opening of the carbureter will operate to heat the gasolene that will enter the chamber 8 and come in contact with the bare wire 7 which is heated when connected to a source of current supply. lhe hot vapor will immediately force its way out through the nearest outlet, namely, through the nozzle, causing the gasolene located above it to flood over the nozzle and at the same time heat the gasolene which, on account of its heated condition, and vaporization, even in cold weather, readily mixes with the air, thus greatly reducing the amount of gas and oil required for starting the engine. it also operates to prevent the accumulation of water in the carbureter since the heat of the resistance'coil vaporizes any water. that enters the chamber 801 the plug.

Bymy invention is thus provided a simple and eflicient vaporizer plug applicable to a great variety of carbureters of different manufacturers.

I claim: V 1. In a carbureter, a nozzle, a resistance Wire located adjacent the passageway of the carbureter leading to the nozzle and located beneath the nozzle for heating the liquid of the fuel as it passes to the nozzle, and means for connecting the resistance Wire to a source of current supply.

2. In a carbureter, a vaporizing plug having a metallic shell, a ceramic body located in theshell, a resistance wire supported by the ceramic body, and means for connecting the resistance wire with a source of current supply.

3. In a carbureter, a nozzle, a varporizing plug having a metallic shell, a tubular ceramic body, the interior of the ceramic body located and communicating with the inte rier of the nozzle, a resistance wire located in the ceramic body, and means for connecting the resistance wire with the source of currentsupply.

In a vaporizing plug, a shell, a tubular member of ceramic material located in the shell and having a flange, packing rings and a packing nut for sealing the tubular member in the shell, resistance w e connected to the shell and located in thetubular member, and meansfor connecting the tubular member with a source of current supply.

In testimony whereof I have hereunto subscribed my name to this specification.
